Specification of Letters Patent,

Patented Feb. 12, 190?.

Application filed March 5,1906. g ialh o. 304,367-

Be it known that I, Jenn S. Srnvnnson, a citizen ol' the United States of America, re-

siding at Detroit, in the county of Wayne and lit-ate of illichigan, have invented certain new and useful improvements in Vehicle- Wheels, of which the iollo ring is a specification, reference being had therein to the accompanying drawings;

My invention relates to nrovements in vehicle-wheels, and particuiarly to hubs therefor, and consists in a novel construction and arrangement of parts whereby a pneumatic or other resilient membet is provided in the wheel-hub.

The object of my invention is to remove the resilient portion of the Wheel from the tire where it is subjected to serious strain and wear and to place it in the hub Where it will be protected and where the only strains and Wear to which it is subjected will be those resul ting from jars and unevenness in the pavement over which the vehicle is running. The means by which I have attained this ob ect null. be more fully hereinafter described, and

set forth in. the claims. 1

In the drawings, Figure 1 is an elevation of my improved hub with portions broken away, and Fig. 2 is a crosssection on lines aztofliigl. I

.Ais the shaft or axle, on which is secured the central or inner hub B by means of a key a. A is the axle-sleeve or housing, and A is a ball-race for balls a acting on the bearing a on the inside of the hubB. The axle or shaft may be secured to the hub 1n any su1t able manner, and the bearing may beconstructed in any of the wayswell known to those skilled in the art without departing from the scope of my invention, so I will not further describe them.

C is the outer or annular hub and is spaced from the hub B, and the inside of hub C and the outside of hub B are provided at t'heir edges with the annular lugs or flanges c 'c and I) b, respectively. These lugs or flanges are curved or hook shaped incross-section to enga e the flanges d on the complementary annu ar members I) I). These members are preferably formed of heavy rubber or other suitable material, and their web portions-to Wit, the portions extending between the hubs-are preferably segmental in cross-sec? new and useful im-- ably annular, and. when inflated completely fillingthe space between the members, and thus locking said members in position. Inflation is provided. for at the nipple e. On opposite sides of the hub C are annular plates F, slightly curved in cross-section and radially ribbed at I, secured thereto by. bolts or lag-screws F and forming flanges bridging the space between the hubs an overlapping" the hub B. G G are parallel apertures at radially-located points in the hub B, and H H are bolts connecting the plates F and passing-loosely through said apertures. The inner edges of the plates F are preferably struck up to term flanges J J, and the edges of these plates contact, respectively, with a flange K on the axle-sleeve and the flange L on the hub B. I have shown the flange L as screw-threaded on the hub B and forming a cap for the end of the axle, but this is not essential. Outside of the flanges J J, I place suitable packing-ringslvi, and thus exclude dust and dirt from the bearings and the inner hub and resilient member. .On the outside of the hub C are the spokes N, thefelly O, the rim P, and a suitable tire R.

As the construction of these elements is riot essential, I shall not further describe them.

From the above description it will beseen that all strains or jars to which either hubis subjected must be transmitted to. the other hub through the medium of the resilient member. The flange-plates ,F- take up all side thrusts,and each hub can move independently a distance equal tozthe radius of the apertures G.

What I claim as my invention is- 1. in a hub for vehicle-wheels thecombination with a central member, of an annular member therearound, compleme1'1tarymemhere between and secured to said central'a'ird annular members and a resilient member be- 1 members, for the 'tral hub, members passing loosely through said apertures and connecting said flanges and a resilient member between said hubs,

for the purpose described.

4. In a vehicle-wheel the combination with a central hub having radially-located parallel apertures therein, of an annularhub member between said hubs,

around and spaced from said central hub, annular plates secured on opposite sides of said annular hub, forming flanges overlapping and flanges on opposite sides of one of said hubs an overlapping the other, for the purpose described.

'6. In a vehicle-wheel the combination with an inner and an outer hub, of a yielding flanges on opposite sides of one of said'hubs and overlappingthe other'hub and bolts connecting said assing loosely through aperflanges and tures in said astementioned hub.

47. In avehicle-wheel the combination "with an inner and an outer hub, of complegmentary yielding members between and secured to said hubs and a resilient member between and supporting said dyielding members, for the purpose describe In a vehicle-wheel the combination Withan inner and an outer hub, of'a yielding member between said hubs, a flange on said outer hub overlapping said inner hub, a

flange on said inner hub contacting with saidfirst-mentioned flange and a" packing-ring associated therewith, for the purpose described.

In testimony whereof I aflix my signature in presence of two Witnesses. v
